How To Paint Inside Of Fireplace (Quick and Easy Guide)

There is no better feeling than getting cozy by a fire with your favorite drink as winter sets in – especially if your fireplace looks incredible.  

Knowing how to paint the inside of your fireplace is the first step in tying together your home décor while hiding any soot. Read on to discover our hacks for painting your fireplace. 

How To Clean & Prepare Your Fireplace Before Painting 


  • Ventilated area 
  • Face mask 
  • Rubber gloves 
  • Protective gloves 
  • Damp rags 
  • Stiff metal brush 
  • Dishwashing liquid 
  • ½ cup of trisodium phosphate 
  • 1-gallon water 
  • Sandpaper or blocks from 100-220 grit (brick and metal) 
  • Brick-patching compound (optional) 
  • Degreaser (optional) 
  • Fireplace caulk (optional, brick) 


Sweep out the dust, ash, soot, and creosote from the sides and floor before going over everything with a hoover. You may need to do this multiple times or employ a TSP and water mixture with the brush to get into all the crannies. Once it is clean, wipe the area with a rag and give the fireplace 24 hours to dry. 


For brick fireplaces, you may want to use a brick-patching compound or fireplace caulk according to their manual instructions to get an even surface.

Once applied, sand the fireplace down with your sanding equipment, starting low and working your way up until you are satisfied. Once done, clean away the dirt and brick dust. 

For metal surfaces, we recommend going over them with a degreaser first before sanding and cleaning them as above.

Painting Different Types Of Fireplaces

Brick-Lined Wood Burning Fireplaces 

Need to know how to paint inside of fireplaces with bricks? Brick fireplaces are one of the more common styles due to their high heat resistance and easy construction. Using non-flammable paint that is heat resistant to 1200 degrees can help conceal soot and creosote stains in the long term.  

However, matte black is not the only color available; it is possible to get a wide range of colors. However, most people choose dark colors such as black and grey as they conceal soot and do not require much maintenance. 

In addition, it is possible to get either liquid or spray paint; spray painting brick is easier to handle, but liquid paint gives you more control over the look and finish. 

Metal-Lined Wood Burning Fireplaces 

Are you wondering what paint to use inside metal fireplaces? Newer fireplaces tend to be made of metal which, while stylish, can be harder for the paint to bond with. 

Heat-resistant non-flammable paint that is suitable for metal surfaces is vital to ensure that your paint job lasts. Matte rather than gloss would be the best choice in terms of finish and aesthetics. 

Gas Fireplaces 

Can you paint inside a gas fireplace? Yes, but it can be a little trickier. Gas fireplaces are typically metal-lined and mean that you do not need to worry about creosote and soot.

However, they will need to be touched up more often than their wood-burning counterparts. Finding paint that is specifically formulated for gas fireplaces or appliances and can bond to metal in high-heat environments is essential.
